The original XML Notepad was written in 1998 by Murray Low in C++, but was eventually removed from Microsoft Developer Network (MSDN) due to its lack of support for modern XML standards and no maintenance. However, because of high demand, a replacement was written in C# by Chris Lovett using the System.Xml library of the .NET Framework 2.0.
XML Notepad 2.6 was released in 2014 containing various bug fixes reported by community on codeplex. It was also updated to use .NET Framework 4.0. According to the Codeplex Web site it moved in 2016 to GitHub.
